# Sumsub

If you already run Sumsub KYC on your users, a lighter server-to-server model is possible where the integration partner acts as a **reusable Sumsub KYC provider** for Mt Pelerin:

* Mt Pelerin can reuse the existing Sumsub applicant id instead of running its own verification from scratch, which removes most of the KYC integration work on the wallet side.
* On our side, this requires a dedicated KYC-fulfillment endpoint that accepts a Sumsub applicant reference, validates it server-to-server, and raises the user's `kycLevel` accordingly.

If you are interested in being a Sumsub-reuse partner, please [contact us](https://www.mtpelerin.com/contact).
